The station opened on 21 June 1921 as the terminus of the then Sanuki Line which had been extended westwards from Iyo-Doi. It became a through-station on 1 May 1923 when the line was further extended to Nyūgawa. At that time the station was operated by Japanese Government Railways, later becoming Japanese National Railways (JNR). With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.

On 25 September 2017, JR Shikoku completed a barrier-free upgrade project for the station. The existing footbridge linking the platforms was replaced by a new bridge equipped with elevators.
